IMPROVEMENT lN MACHINES FOR LINING PASTEBOARDS.

Specification forming part of Letters Patent NO. 111,849, dated February I4, 1871.

To all whom t may concern.'

' Be it known that I, GUSTAV L. JAEGER, of the city, county, and State of New York, have invented a new and Improved Machine for Lining Pasteboards and for pasting two sheets of Ypaper together; and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of this specification, in which draw- 1n g- Figure l represents a longitudinal vertical section of this invention, the line .r a', Fig. 2, indicating` the plane of section. Fig. 2 is a plan or top view of the same. Fig. 3 is a detached elevation of the spiral brush, which serves to spread the paper on the paper-cylinder.

Similar letters indicate corresponding parts.

This invention relates to a machine for 1ining pasteboards with paper, or for uniting two sheets of paper, said machine being colnposed of apasteboard-cylinder, provided with gripers capable of taking hold ofthe pasteboards and carrying them past a pasting-roller, and then bringing them in contact with sheets of paper carried on a paper-cylinder, and held thereon by gripers, in combination with a y which serves to carry oif the lined pasteboard.

A spiral roller-brush spreads the sheets of paper on the paper-cylinder, so that the same will lie Hat and show no wrinkles after having been pasted to the pasteboard.

In the drawing, the letter A designates a frame, by preference made of cast-iron, which forms the bearings for shafts B O I), on which are mounted, respectively, the pasteboard-cylinder E, the pasting-roller F, and the papercylinder Gr.

The pasteboard-cylinder is constructed with a raised segment, a, which is covered with india-rubber, felt, or other similar material, like the paper-cylinder of a printing-press.

Close to the shoulders, which form the connection between the raised segment of the pasteboard-cylinder and its low section, are situated two shafts, b b', which extend across the cylinder, and carry each a series of gripers, c c', intended to clamp the pasteboard and retain the same securely on the snrfaceof the cylinder.r A

The shafts b b' extend beyond the cylinder,

vand on theirv ends are mounted arms .d d',

which act against a stationary cam, 1I, secured to the frame A, and as the cylinder re volves in the direction ot'lthe arrow marked thereon in Fig. 1l the .arin' d of the shaft b strides the cam H, and the gripers close down upon the end of the pasteboard fedto the cylinder E over the tableAI. l The pasteboard is thus drawn in, and it is held down upon the surface of the raised segment c of the cylinder by a roller, J, which bears down by its inherent gravity and prevents the `pasteboard from springing out away froml the surface of the cylinder, so that the outer edge of the board will be clamped by the gripers c.

The pasteboard, being thus held down upon the surface of the cylinder E, is carried past the pasting-roller F, which is covered with felt or other absorbent'material, and geared, together with the cylinder E, so that its superiicial velocity is considerably less than that of said cylinder.

The shaft C of the pasting-rollers has its bearings in boxes which slide in slots in the frame A, so that the position of the pastingroller, in regard to the pasteboard-cylinder, can be adjusted by set-screws f with the greatest accuracy.

The pasting-roller dips in troughs K oontaining paste, and, as the same revolves, it takes up some of the paste and rubs the saine against the pasteboard carried on the pasteboard-cylinder, the surplus paste being scraped off by reason of the difference in the circumferential velocity of the pasting-roller and the pasteboard-cylinder.

The paper-cylinder Gr is geared, together with the pasteboard-cylinder E, by cog-wheels l, (see Fig. 2,) so that the circumferential velocitypf the two is exactly alike, and said paper-cylinder isfurnished with one set of gripers, m, which take hold of the sheet of paper fed to said cylinder over the table L and carry the same through between the two cylinders, bringing it in contact with the surface of the pasteboard which has been previously covered with paste.

Before the paper is brought in Contact With the pasteboard, however, it is exposedto the action of a spiral cylinder-brush, M, a de- A tached View ci' which is shown in Fig. 3. By

After the paper has been brought in contactv with the pasteboard, both the sheet of paper and the pasteboard are released by their gripers, and thelined pasteboard is deposited on a fly, P, a series of tapes, n, being provided, which prevent the paper from adheil` ing to the paper-cylinder. These tapes are stretched over the paper-cylinder and over sectional rollers N, and they run down between the arms of the fly, which is constructed similar to a :dy of a cylinder printing-press. Said y has its fulcrum on a shaft, o, mounted in the frame A, and carrying a pulley, p, round which is wound a cord, q, one end of which is secured to an eccentric-pin, r, secured in thev board previously deposited on the ily P is v turned down upon the table O. This table is supported by springs t, which yield as the Weight of the pasteboard on the table increases, so that the surface presented to the ily remains as near as practicable at a uniform level, and that the fly, on being turned down, will receive no injury.

If desired, the ly can be made to deposit the pasteboard on an endless apron, serving to carry the saine to the drying apparatus.

It must be remarked that the paper might be fedV over the cylinder E and the pasteboard over the cylindery Gr, and the cylinder E might be so arranged that its raised segment could be adjustedvto sheets of different sizes.

What I claim as new, and desire to secure Yby Letters Patent, is-

1. The pasteboard-cylinder. provided with gripers c c', in combinati-on with the pastingroller F and with thefpapercylinder G, all constructed and operating substantially in the manner herein shown and described.

2. The spiral cylinder-brush P, in combination with the paper-cylinder G and the pasteboard-cylinder- E, substantially in the manner set forth. l y 3. The'combination of the yielding table O with the ilyv P, the paper-cylinder G, and the pasteboard-cylinder E, substantially as described.
